What is a ferromagnetic substance?
Understanding Ferromagnetic Substances Ferromagnetic substances are materials that exhibit strong magnetic properties when exposed to a magnetic field. These materials have the ability to retain magnetization even after the external magnetic field is removed. In this article, we will delve deeper into the nature of ferromagnetic materials and explore how they work. Characteristics of Ferromagnetic […]
What is a geomagnetic storm?
Understanding Geomagnetic Storms: The Basics A geomagnetic storm is a natural phenomenon that occurs as a result of sudden changes in the Earth’s magnetic field. These changes happen when the Earth’s magnetosphere, which is the region surrounding the planet that is dominated by the magnetic field, interacts with the solar wind – a stream of […]
What is magnetic levitation?
Understanding Magnetic Levitation Magnetic levitation, or maglev for short, is a type of transportation technology that allows vehicles to float above a track using magnetic forces. Instead of relying on wheels or other contact points, maglev vehicles are suspended in the air by magnetic fields, allowing for faster, smoother, and more efficient travel. How does […]
What is the difference between diamagnetism and paramagnetism?
Diamagnetism vs. Paramagnetism: Understanding the Difference Have you ever come across the terms diamagnetism and paramagnetism and wondered what they actually mean? These two concepts refer to the magnetic properties of materials and it’s important to understand the difference. Here’s a breakdown of what distinguishes diamagnetism from paramagnetism. What is Diamagnetism? Diamagnetism refers to a […]
What are magnetic domains?
Understanding Magnetic Domains: An Introduction In simple terms, magnetic domains refer to the microscopic magnetic regions that make up a magnetized material. These domains represent specific areas within the material where the magnetic field is uniform, and the magnetic moments of individual atoms are aligned in the same direction. Understanding magnetic domains is crucial in […]
How does magnetism affect living organisms?
What is the relationship between magnetism and living organisms? Magnetism is a fundamental force of nature and it is known to influence living organisms to some extent. The earth’s magnetic field is necessary for life as we know it and it directly influences the orientation and behaviour of many animals. However, the impact of magnetism […]
What is magnetic hysteresis?
Understanding Magnetic Hysteresis Magnetic hysteresis is a phenomenon that occurs in materials when they are exposed to an external magnetic field. Simply put, it refers to the lag in the magnetization of a material when the magnetic field is changed. This phenomenon is widely used in various applications, ranging from the production of magnets to […]
What is magnetic permeability?
Understanding Magnetic Permeability: The Basics Magnetic permeability is an important concept in the field of electromagnetism, and refers to the ability of a material to conduct magnetic fields. It is defined as the ratio of the magnetic flux density to the magnetic field strength, and is typically denoted by the Greek letter mu (μ). This […]
What are eddy currents?
Understanding Eddy Currents Eddy currents, also known as Foucault currents, are circular electric currents that are formed when a conductor is exposed to a changing magnetic field. These currents circulate within the conductor in a direction that is perpendicular to the magnetic field. The Science behind Eddy Currents Eddy currents are produced because of electromagnetic […]
What is a magnetic field line?
Understanding Magnetic Field Lines: Explained in 5 Paragraphs If you have ever played with magnets, you might have seen the iron filings arranging themselves in unique patterns. These patterns illustrate the magnetic field lines of the magnet. What Is a Magnetic Field Line? A magnetic field line is an imaginary line that depicts the direction […]
